COOKER.

Specification o1' Letters Patent. Y Patented Blur. 12, 1918.

Application led June 24, 1916, Serial No. 105,712. Renewed J'uly 12, 1917. Serial No. 180,289.

To all whom t may concern Be it known that I, ALFRED M. DEMUTH, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, haveinvented new and useful Improvements in Cookers, of which the following is a specication.

rThe present invention relates to improvements in apparatus for cooking food in its own juices and without immersing the same in water, and the object of the invention is to provide an apparatus of this character in which a vertical series of vesselscan be emv ployed in the same boiler and in which the vessels `can be easily and quickly removed and replaced without danger of injury to the operator by the heat required for cooking.

In the accompanying drawing, Figure-1 is a longitudinal section of my improved cooking apparatus; Fig. 2 is a cross section 0f the same on the line 2 2 of Fig. 1; Fig. 3 is a longitudinal vertical section of a modified form of the invention; Fig. 4 is a cross section of the same.

Referring to the drawing, 1 indicates a boiler, here shown as rectangular in cross section. In the top 2 of the boiler is a rectangular opening, and to the edges of the top around the opening are secured, by angle irons 3, depending plates or walls 4, which hold down an angle iron 6 secured to the outer surface of the top of al rectangular cooker 7, said cooker being supported by Iugs'8 secured to its bottom and resting upon the bottom of the boiler. Handles 9 are provided at the ends of the top of the boiler, and a cover 11, hinged, as shown at 12, closes the opening in its top, said cover having near its free edge a handle 13. In the top of the boiler is a safety valve 14. The cooker is closed at the top by a cover 16, handles 17 being provided for lifting the cover from the cooker.

In the cooker is a vertical series of cooking vessels 18, all interchangeable with each other (two only being here shown), each cooking vessel having fiat sides and a rounded bottom and having legs 19 secured to, and depending from, its bottom, and bent, as shown at 21,`so as to be capable of resting upon the upper edge of the next lower cooking vessel of the series as well as being able to 'rest upon the bottom of the cooker. At the ends of each cooking vessel are secured T-shaped handles 22. A thermometer 23 serves to indicate the temperature. To the bottom of the cooker, around a hole 2-1 therein, is riveted a plate 26 in which is secured a pipe 27 extending through a hole in a side of the boiler near the bottom, having a collar 28 secured to the pipe against The form of the invention shown in Figs. l l3 and 4 is best yadapted for cooking vegetablesthe cooker being round, instead of rectangular, and therefore .having no corners in its interior. I have herein shown the cooker used as a cooking vessel.

By reason of the walls4 contacting at their lower edges with the angle plates 6` no steam can pass from the boiler to injure the person of the attendant, and furthermore, the walls 4 and angle irons 6 prevent the steam or vapor from the boiler -1 from entering the vessel 18, so thatthe food in the vessel will be cooked in its own juice.

By means of the above-described invention, all kinds of meats, vegetables, and fruits, can be cooked in their own` juices and without the admixture yof water, the resulting product being found to be very superior to these edibles as ordinarily cooked by mixing with water, as they retain the original flavor in a very high degree.

When it is desired to remove the cooker from the boiler, the boiler cover can be removed by unscrewing thumb nuts 37 onv screws 38 which extend through lugs 36 depending from said boiler cover and thus attach it to the boiler.

The arrangement of the pipe leading to the faucet inthe vbottom of the, cooker vpermits of the cooker being thoroughly cleansed. The faucet can also be removed from said pipe and itself cleansed.

I claim Y 1. In a combination, a boiler, a top therefor having an opening therein and a wall depending therefrom around said opening, a cooker in said boiler, its top extending above the bottom of said wall but below the top of the boiler, said-cooker being provided withA means extending beneath, andinto close contact with, said wall, yfor preventingy the'v cooker in said boiler, its top extending.

above the bottom of said wall but below the 1liV htopof theboiler, and an angleiron secured i f..to,and around the cooker and extending beneathyandI into4 close contact with, said wall fto preventthe passage of! steam 'l into the i spacewithin thev wall and above the cooker.
